The mono propylene glycol solution is a synthetic option that has no color, is odorless, and doesn’t taste like anything. What Does Coolant Do?Ĭoolant contains several alcohols that are either mono ethylene glycol or mono propylene glycol. You will find HOAT coolant in many vehicles like Volkswagen, Ford, Volvo, Mercedes Benz, Audi, KIA, Hyundai, Nissan, Honda, Toyota, and many more. HOAT antifreeze will often be labeled with terms like G-05, G-11, G-12 and Global, and you need to check your owner’s manual to see which type your car requires. This is a much longer service life than some other types of coolant. This type of coolant should be flushed every 100,000 miles or every five years, whichever one comes first. It’s meant for newer cars, with some of the top manufacturers recommending it. HOAT Coolant contains added silicates for additional protection against rusting or corrosion of the aluminum parts. While it is normally yellow in color, you can also find it in purple, blue, pink or turquoise. This coolant type is a combination of OAT (Organic Acid Technology) and IAT (Inorganic Acid Technology). HOAT means Hybrid Organic Acid Technology, or Hybrid OAT. But if you mix a significant amount of one type in with the other type, you're weakening your corrosion inhibitors (it happened to my brother, and look at the condition he's in now).Does it matter what brand of coolant I use? What is HOAT Coolant? You can mix two different colors of the same kind of coolant without any problem whatsoever. Color doesn't tell you what you really need to know. RAY: So that's the story on coolant color, Jeffrey. But it would be prudent, during your next service, to drain out a mixed batch of coolant and go with one type or the other. And even if the rust-inhibition properties were compromised, you could still go a year or even several years without any negative effects. As we said, nothing is going to break, burn up or melt. But if you go beyond that 15 percent threshold, then it makes sense to EVENTUALLY drain out the coolant and fill it up with all one or all the other. So if, for example, you just top up your OAT coolant with a few cups of traditional stuff, nothing's going to happen. RAY: The experts we spoke to at SAE (the Society of Automotive Engineers) said that you can mix up to about 15 percent traditional coolant in your OAT coolant before you have any real effect on the corrosion inhibitors. (There's usually a decal under the hood that tells you if your car came equipped with long-life coolant.) Your mechanic may have noticed that the color was diluted with something else, and he may have assumed you mixed a traditional coolant with your OAT coolant. So that's what was probably in your car, Jeffrey. TOM: General Motors has been using an orange-colored OAT coolant since about 1994. And if you mix the two types of coolant, nothing terrible is going to happen - nothing is going to blow up or melt - but a mixture of the two types of coolants won't have as much rust protection as either one individually. RAY: The difference is that the OAT coolant has rust inhibitors that last 100,000 miles or more, whereas traditional coolants have rust inhibitors that only last 50,000 miles or so. And then there's the newer, "organic" coolant - also known as OAT, or Organic Acid Technology. There's "traditional" coolant, which is what we've been using forever. TOM: There are basically two types of coolant in the world. So it gives you a hint as to the identity of the coolant's manufacturer, but it doesn't tell you what type of coolant it is, and that's the more important question. Prestone has always used fluorescent yellow, Texaco and Shell have always used green. It's added by the manufacturer as an identifier. The color in antifreeze is like food coloring. RAY: From an automotive point of view, however, it's a more complicated question. ![]() And he said that under no circumstances should you ever mix pink and green. TOM: Well, we checked with our interior decorator, Franc. Could it be due to the little bit of pink antifreeze I added to the green? - Jeffrey Since then, he informed me that my head gaskets needed replacing. He stated that one cannot mix colors of antifreeze (pink and green, in my case). He told me he had to flush the radiator because I had added a different color antifreeze to my cooling system. ![]() Many months ago, my trusted mechanic was making repairs to my 1995 Chevy Lumina.

![]() Another group was sold at the Mayor Gallery after being exhibited with two other primate artists in 2005 in a show called “Ape Artists of the 1950’s.” That same year, three of Congo’s paintings sold for a combined $25,000 at auction, 20 times the expected price. Most of Congo’s 400 works of art were sold after the 1957 exhibition. People would imagine he’d just grab a pencil or a paper, but.he’d have several colors and he'd think before he painted.He was extraordinary.” Speaking with Rory Sullivan of CNN, Mayor declares that the chimp’s paintings are “actually very good…He was a fascinating painter. James Mayor, director of the gallery that will show Congo’s work, also praises Congo, who died of tuberculosis in 1964 at the age of 10. “Watching him paint was like witnessing the birth of art.” “Congo’s ability to make a controlled abstract pattern and then to vary it in different ways meant that inside the ape brain there was already an aesthetic sense-very primitive but nevertheless present in a non-human species,” he says. Rather, as he tells Taylor Dafoe at artnet News, it’s what Congo’s art represents that's most important. ![]() Upon viewing Congo’s work, Salvador Dalí quipped the “hand of the chimpanzee is quasihuman the hand of Jackson Pollock is totally animal!”Īs Morris explains, “The more serious the artist, the more they understood what Congo was doing because they could see that he was positioning his lines.” That being said, he cautions people from overhyping Congo’s artwork. ![]() Joan Miró swapped two of his pieces for one of Congo’s 400. Art world luminaries including Picasso bought his work. In 1957, Congo’s work went on display at the Institute of Contemporary Arts in London. Morris went on to feature the painting chimp on “Zoo Time,” and he became something of a sensation. “And if I tried to persuade him to go on painting after he considered that he had finished a picture, he would stubbornly refuse.” If I tried to stop him before he had finished a painting, he would have a screaming fit,” Morris says. Congo became increasingly obsessed with his regular painting sessions. While he never made any representational art, he did appear to have some chops when it came to abstract work, favoring a radiating fan pattern. Morris realized Congo could make circles and even had a sense of composition he filled in parts of the paper to balance his drawings. Would it happen again? Yes, it did, and again and again.’” It wandered a short way and then stopped. “This is how I recorded it at the time, ‘Something strange was coming out of the end of the pencil. “He took it and I placed a piece of card in front of him,” Morris recalls. He’s also the author of many popular science books, including 1967’s The Naked Ape, which examines humans through a zoologists lens.Īs Nigel Reynolds at the Telegraph reports, one day Morris offered the young chimp Congo a pencil and the rest was history. He was a noted abstract painter, an ethologist (someone who studies animal behavior) and zoologist. show broadcast from the London Zoo in the 1950s. The paintings are owned by Desmond Morris, who hosted “Zoo Time,” a U.K. In December, a beloved 20th-century artist will finally get his due when a lot of 55 paintings by Congo the chimpanzee goes on exhibit at the Mayor Gallery in London. |
